[Solver] Error updating deps after adding AsseticBundle

[jmikola]

My project's composer.json file looked like this:

{
    "require": {
        "doctrine/data-fixtures": "master-dev",
        "doctrine/mongodb-odm": "master-dev",
        "jms/security-extra-bundle": "master-dev",
        "monolog/monolog": "master-dev",
        "sensio/distribution-bundle": "master-dev",
        "sensio/framework-extra-bundle": "master-dev",
        "sensio/generator-bundle": "master-dev",
        "symfony/mongodb-odm-bundle": "master-dev",
        "symfony/symfony": "2.1.0-dev",
        "twig/twig": "1.4.0-dev"
    }
}

Running ./composer.phar install --dev downloaded all of the deps (and VCS info) just fine. I then added the following dependency:

        "symfony/assetic-bundle": "master-dev",

And re-ran: ./composer.phar update --dev, which yielded the error:

[arsjerm.net] master $ ./composer.phar update --dev
> Updating dependencies.

If I wipe out my lock file and vendors/ directory, re-installing all of the deps (including AsseticBundle) works fine.

This have happend quite a few times for me aswell with other various bundles.

I think I've hit the same problem today. Here are the steps to reproduce:

I've added the following composer.json to an empty folder:

{
    "require": {
        "symfony/symfony": "v2.0.6",
        "twig/twig": "v1.1.2",
        "monolog/monolog": "1.0.2",
        "doctrine/common": "2.1.*",
        "doctrine/dbal": "2.1.*",
        "doctrine/orm": "2.1.*",
        "kriswallsmith/assetic": "master",
        "twig/extensions": "master",
        "metadata/metadata": "master",
        "swiftmailer/swiftmailer": "v4.1.3",
        "sensio/framework-extra-bundle": "master",
        "jms/security-extra-bundle": "master",
        "symfony/assetic-bundle": "master",
        "sonata/admin-bundle": "master",
        "knplabs/knp-menu": "1.0"
    }
}

Then I've ran php composer.phar install

Later, I've added "knplabs/knp-menu-bundle": "master" to the json file, ran php composer.phar update and got the same error:

> Updating dependencies.

I've downloaded the composer sources and tried to run it once again to see the actual error line numbers. Here they are:

Solver.php line 1503 references $this->learnedLiterals, which seems to mean $learnedLiterals (since there are no learnedLiterals property in the class). However, fixing it didn't help to cure the problem. Somehow the analyze() method comes to a point where it tries to process negative $decisionId.

From just quickly looking into the code I can tell that it's something wrong with $l1num variable. The only exit conditions of the outer loop is !$l1num (seen 2 times preceding break 2 statement), however $l1num is never decreased inside the loop.
Probably $l1num = 0 initial assignment should be moved inside the outer while (true) loop. I've tried and it helped. But this is just a GUESS, unfortunately I didn't have time to get deep into this.

this issue should be fixed with #147

[kostiklv]

No, the fixing the typo doesn't fix the problem - see the second half of my

@naderman this seems an issue for you

[naderman]

Should be fixed now. Please try again.

This still fails, but I'm inclined to think it might be a package database error because GitHub was offline again today:

This is just because there is no "master-dev" release of assetic-bundle. Use 2.1-dev.
